StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 28 June 2026; the live site may have changed since.

Schema Source by Tabstack is largely in shape, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: missing several security headers and no sitemap.

Launched on Product Hunt on June 28, 2026. The site is hosted on Google LLC in the United States, with a domain registered in 2025. The crawl picked up 9 technologies on this site, covering ui library, analytics, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Google Analytics, and Google Fonts.

For context, it's on one of the most common stacks we track, shared by 5,172 launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
